Doc Cam Resolution Reset

The Lumens document camera is one of the most powerful teaching tools attached to the Innovation Station.  The doc cam's image capture feature is a great way to capture an image for students to use with their notes, in their digital work, or for a lesson resource.

When using the Doc Cam input, one can push the 'Capture' or 'Record' button to save images to the SD card placed into the doc cam base.  One will get a visual cue that capturing is happening by seeing a rotating hourglass in the top left or 'Recording' in the top right during video capture. 

Occasionally, the user will not see these visual cues when image capturing. Usually, the reason is because the resolution of the doc cam has changed and needs to be reset. The solution is pretty easy.

Teachers can quickly see if they need to change the resolution by pushing the menu button on the base of the doc cam. If the top four menu tabs are visible, then your doc cam is presenting at the correct resolution.

If the top menu tabs are cut off or running off the top of the screen, the resolution needs to be changed. Using the arrow keys on the base of the doc cam, press the right button (3 times) until you see the line "Output Mode" on the screen. Push the down arrow key until Output Mode selection is highlighted. It probably says 'SXGA'. Once highlighted, push the right button to select 'UXGA' and then the enter key on the base. The screen will flash and return to full resolution.

Your doc cam is now ready to show a high quality image which can be captured for classroom use.

What innovative way have you used the document camera? How have you used captured images with your class?
